FIELD OF THE INVENTION

This application claims priority to U.S. Provisional Patent Application No. 62/077,155, filed on Nov. 7, 2014, the entire contents of which are incorporated by reference herein.

BACKGROUND Field of the Invention

The present invention relates to systems and methods for authenticating or identifying articles that may move in a theatre, and in particular personnel and personnel related material.

Description of Related Art

Valuable articles are counterfeited or fraudulently represented. Life-saving products are always high value, and regrettably, disproportionately targeted by the bad actors that commit these crimes.

As a well-known example, counterfeit and substandard antimalarial drugs were documented to have appeared in Africa shortly after their development, yet the media recently reported on how these fakes continue to undermine years of progress in treating and reducing the incidence of disease there. In the absence of proper planning and control, counterfeit and substandard personal protective equipment (PPE) similarly will thwart efforts to treat and stop the spread of Ebola virus.

Additionally, determining identification of articles that may move in a theatre is complex. Exemplary of such articles are persons in many scenarios where they are uniformed, making identification difficult. Examples of theatres include shipyards, warehouses, in military operations, and in health care settings.

There remains a need to address these disadvantages and others not described herein.

BRIEF SUMMARY

According to one embodiment, a method is provided. The method includes providing an authentication code onto a reference article associated with a person, determining a signature associated with the authentication code, imaging a candidate article to determine an image signature, and comparing the associated signature with the image signature to determine whether the candidate article is the reference article.

According to one or more embodiments, the article is a container, such as a shipping container in a shipyard or wrapper around a pallet in a warehouse.

According to one or more embodiments, the article is a garment worn by a person.

According to one or more embodiments, the article is multiple garments worn by a person or layered containers.

According to one or more embodiments, each of the multiple garments or layered containers have respective authentication codes.

According to one or more embodiments, the signature of each respective authentication code is stored in a database and associated with each other.

According to one or more embodiments, a system is provided that includes a server configured for receiving an authentication code associated with a person and determining a signature associated with the authentication code and an imaging device that images a candidate article and communicates the image to the server. The server compares the associated signature with the image signature to determine whether the candidate article is the reference article.

According to one or more embodiments, an imaging device having computer control code thereon that when executed by a processor images an authentication code on a candidate article, communicates the image to a server, and receives, from the server, an indication of authenticity between the signature of the candidate article and a signature of a reference article.

DETAILED DESCRIPTION

With reference now to FIG. 1, a method 10 is illustrated. The method includes providing an authentication code 12 onto a reference article associated with a person.

The authentication code may be any appropriately configured code, including a random code of assigned variables. The code may be any of the codes illustrated in co-pending patent application Ser. No. 13/457,115 filed on Apr. 26, 2012 by the current assignee of this disclosure and application Ser. No. 14/067,945 filed on Oct. 30, 2013, the entire contents relating to the types of code, methods for imagining, methods for generating, and methods for creating a signature are incorporated by reference herein.

The one or more methods provide for authentication and identification (autoID) of an article from a digital image that may come from a simple mobile application on a smart phone or any other digital imaging device, including optical scanners, remote cameras, or video feed. Any smart printer may be used to deliver autoID codes, which do not require special inks or taggants, expensive validation hardware, or proprietary printers.

The reference article associated with a person may be a garment such as a uniform. The authentication code may be provided on the uniform as a code randomly positioned on the uniform or positioned at designated places on the uniform. The code may be produced in distinct or defined limited areas or may be produced to substantially cover the uniform. The code may be sewn on, printed on, painted on, or otherwise adhered or applied on. The garment may be a multi-piece garment. In an illustrative example of a PPE, there might be provided a suit covering the persons torso, arms, and legs, shoes to cover their feet, gloves to cover their hands, and a mask or helmet to cover their face. The same authentication code could be applied to each of the suit, shoes, gloves, and mask or helmet, or alternative or differing codes could be applied to each and the server and system disclosed herein could track the differing codes.

The reference article associated with a container may be a shipping container 28B such as is used for moving freight by ship, train, or truck. Alternatively, the container may be the wrapping of a pallet 28A typically used to move multiple cartons or other items in a warehouse. The authentication code may be provided on the container as described for a uniform, above. The container may be layered, as where multiple pallets are enclosed in a shipping container, or where multiple boxes are wrapped on a pallet. The same authentication code could be applied to each layer, or alternative or differing codes could be applied to each and the server and system disclosed herein could track the differing codes. The container may be any enveloping material capable of concealing or otherwise masking the contents carried therein.

The method may include determining a signature 14 associated with the authentication code. This signature may be a numerical signature that is generated based on the code. Further description of one appropriate methodology is depicted and described with reference to FIG. 5.

The method may include imaging a candidate article 16 to determine an image signature of the candidate article. The imaging may be carried out by any appropriate imaging device including a mobile device having imaging capabilities, a scanner or similar camera, and the like. In one embodiment, an imaging device may be positioned proximal to a check-in or check-out location for medical equipment such as PPE. In these instances, a person may check out equipment by scanning the PPE a first time to determine the reference signature. Alternatively, the reference signature may be determined before the code is ever printed onto the article. In these embodiments, other identifying characteristics of the person checking out the equipment may be monitored, such as facial recognition, finger prints, and the like.

The reference signature and the person are thus linked with an appropriate database such as one maintained on the server. The scanning of the PPE may include scanning of each article of the PPE. In this manner, a person may have, as an example, a mask having a first authentication code and a suit having a second authentication code and the server can associate the mask and the suit together with a particular person even though the codes do not match.

An example of an article or garment such as PPE with authentication code provided thereon is illustrated in FIG. 2.

The method may then include comparing the associated reference signature with the candidate image signature to determine whether the candidate article is the reference article 18. This comparison may be accomplished on a server or may be accomplished on the imaging device or a device coupled to the imaging device.

As illustrated in FIG. 2, the imaging device may include multiple imaging devices 22. For example, in a surveillance setting, multiple imaging devices may be positioned within a floor plan, shipyard, or warehouse space. The imaging devices can thus track location of persons traveling from room to room or into secured or non-secured areas. The signature associated with the code may include information such as the person assigned to the article, the manufacture date of the article, permissions for the person to enter into a portion of a building or access information, and the like. The images may then be provided with reference to a known outline of an imaged area 24.

The first garment 26 may include a first authentication code 32′, a second authentication code 34′, and a third authentication code 36′. The codes may be the same, or different, and may be provided in layers with other information such as the name of the person wearing garment 26. Second garment 30 may include a first authentication code 34′ and a second authentication doe 34″. Codes 34 and 34″ may be different from one another or may be the same but provide on separate portions of garment 30 in order to provide more presentation of the codes for imaging.

A system is thus provided and illustrated in FIG. 3. The system 40 may include a server 42 configured for receiving an authentication code associated with a person or a garment of a person and determining a signature associated with the authentication code. The system 40 may further include the imaging device 22 that images a candidate article and communicates the image to the server. The server 42 is configured to compare the associated signature with the image signature to determine whether the candidate article is the reference article. The server may communicate with the imaging device over a network 44, which may be a WLAN, Cellular, Blue-Tooth, or other near or far range network.

The server 42 may include a processor and a memory. The server is configured for receiving an authentication code associated with a person and determining a signature associated with the authentication code, receiving an image having an authentication code from an imaging device, determining a signature associated with the authentication code of the received image, and comparing the signature associated with the authentication code of the received image with a reference signature to determine whether the candidate article is the reference article. In one or more embodiments, the signature associated with the reference authentication code may be pre-determined or provided in a downloadable database. In one or more embodiments, the garment is personal protective equipment having a predefined period of authorized use by the person. In one or more embodiments, the server is configured for receiving a subsequent image at a subsequent time from the imaging device. In one or more embodiments, the server is configured for displaying, on a user interface, a map outline of the received images with reference to a known outline of an imaged area. In one or more embodiments, the article(s) are multiple garments worn by a person. In one or more embodiments, each of the multiple garments have respective authentication codes. In one or more embodiments, the signature of each respective authentication code is stored in a database. In some embodiments, the reference article is a garment worn by a person or a container. In some embodiments, the authentication code of the multiple garments worn by the person or of multiple layers of the container are not the same, the server configured to match differing authentication codes corresponding with the multiple garments worn by the person or multiple layers of the container. In one or more embodiments, the server is configured for receiving a second image having an authentication code from a second imaging device.

Relevant information associated with a person or article as illustrated in FIG. 2 is illustrated in FIG. 4, along with a floor plan for use in a surveillance setting. Captured images and signatures may be used to track movement of a person on the floor plan.

An imaging device having computer control code thereon that when executed by a processor is thus provided. The computer control code is configured to image an authentication code on a candidate article, communicate the image to a server, and receive, from the server, an indication of authenticity between the signature of the candidate article and a signature of a reference article.

In these one or more methods and embodiments disclosed herein, advantageously there is provided methodologies for line-of-sight tracking of personnel or containers in a theater or other setting. This presents an advantage over certain radio-based or other frequency based technologies where such tracking is undesirable (such as effect on medical equipment or a way for the interrogator to be track which would thus be undesirable in a military setting) or where the signal noise from such crowded tracking would be undesirable.

As illustrated in FIG. 5, the signature may be generated from processing a plurality of elements present on an article. These elements may be described using a set of source likenesses and given numerical similarity score or a collection of numerical similarity scores. A similarity score or a set of similarity scores may be calculated by comparing a location in the article to a predefined shape or set of shapes. This comparison may be done by using an image representation of the location on the article and performing a correlation operation between the image representation and an image representation of the shape or set of shapes. This operation may produce a similarity score or set of similarity scores from the result of the correlation operation. The signature may contain the similarity score or the collection of scores. The collection of similarity scores can be stored and they can also be compared to determine similarity between two sets of such scored. These elements may be represented as a digital image and processed by a software code which calculates the aforementioned similarity scores. The software code may also compare two sets of scores to determine similarity between scores in the set or the sets as a whole.
